For example, the detecting unit 140 can detect aposition of the wearable device 200 via image processing. In order todetect a position of the wearable device 200, the detecting unit 140 caninclude one or more image sensors and/or proximity sensors. Thedetecting unit 140 can detect a position of the wearable device 200using a magnetic field and/or an electric field. For example, thedetecting unit 140 can include one or more magnetic field sensors and/orelectric field sensors located at a different position. The detectingunit 140 compares values measured by the electric field sensors and/orthe magnetic field sensors located at a different position with eachother to detect a position of the wearable device 200. The detectingunit 140 can include a touch sensor. The detecting unit 140 senses atouch input caused by the wearable device 200 to sense a position of thewearable device 200.

The detecting unit 140 can sense a position of the wearable device 200by selectively combining the aforementioned sensing methods. Forexample, if a distance between the mobile device 100 and the wearabledevice 200 is equal to or greater than a predetermined distance, thedetecting unit 140 senses a position of the wearable device 200 using animage sensor. If the distance between the mobile device 100 and thewearable device 200 is less than the predetermined distance, thedetecting unit 140 can detect a position of the wearable device 200using a magnetic field sensor, an electric field sensor, a proximitysensor and/or a touch sensor. The aforementioned sensors of thedetecting unit 140 are an example only. It may use sensors of adifferent type to determine a relative position of the wearable device200 for the mobile device 100.

The detecting unit 140 can detect a position of the wearable device 200together with the communication unit 130. For example, the detectingunit 140 can include 2 sensors respectively existing at opposite edges.In this case, the detecting unit 140 measures a distance between thewearable device 200 and the mobile device 100 using the communicationunit 130 and determines a position of the wearable device 200 using thesensors of the detecting unit 140.

The mobile device 100 according to the present specification may notrequire an absolute position of the wearable device 200. In particular,the mobile device 100 according to the present specification may detecta relative position of the wearable device 200 only for the mobiledevice 100. Yet, the mobile device 100 can obtain the absolute positionof the wearable device 200 using a GPS of the wearable device 200.

The processor can control the display unit 120, the communication unit130, and the detecting unit 140. And, the processor 110 can controlother configurations included in the mobile device 100.

And, the display unit 220 can include atouch sensor. In particular, the display unit 220 can include a touchsensitive display unit. The touch sensor can be positioned on thedisplay unit 220 or in the inside of the display unit 220. The touchsensor can sense various touch inputs such as a contact touch input or anon-contact touch input including a sliding touch input, a multi touchinput, a long-press touch input, a short-press touch input, a drag touchinput, a hovering input, and a flicking touch input. Moreover, the touchsensor can sense a touch input inputted by various input tools such as atouch pen, a stylus pen, and the like. The touch sensor can forward aresult of sensing a touch input to the processor 210. For example, thedisplay unit 220 may have a circle shape or a rectangular shape.

The communication unit 230 communicates with the mobile device 100 andcan transmit device information of the wearable device 200 to the mobiledevice 100. The communication unit 230 can receive information from atleast one external device.

Meanwhile, the configuration diagram of the mobile device 100 and thewearable device 200 shown in FIG. 2 corresponds to a block diagramaccording to one embodiment. Blocks represented as being separated showhardware configuration units in a manner of being logicallydistinguished. Hence, each of the configuration units of the mobiledevice 100 can be implemented by a single chip or a plurality of chipsdepending on the design of the mobile device 100. And, each of theconfiguration units of the wearable device 200 can be implemented by asingle chip or a plurality of chips depending on the design of thewearable device 200.

And, operations of the mobile device 100 and the wearable device 200described in the following can be performed by the mobile device 100and/or the wearable device 200 mentioned earlier with reference to FIG.2.

FIGS. 3a to 3c are diagrams for an interface of a mobile device providedaccording to one embodiment.

Referring to FIG. 3a , a first image 301 is displayed on the displayunit 120 of the mobile device 100. A user of the mobile device 100 maywant to transmit a part of the first image 301 to the wearable device200 of the user. For example, the user of the mobile device 100 may wantto use the part of the first image 301 as a wallpaper of the wearabledevice 200.

Referring to FIG. 3b , the user places the wearable device 200 near themobile device 100. For example, as shown in FIG. 3b , the user may placethe wearable device 200 in the vicinity of the rear side of the mobiledevice 100.

As mentioned earlier with reference to FIG. 2, the mobile device 100 candetermine whether or not the wearable device 200 is placed in thevicinity of the mobile device 100 using the detecting unit. For example,if a distance between the wearable device 200 and the mobile device 100is less than a predetermined distance, the mobile device 100 candetermine it as the wearable device 200 is located in the vicinity ofthe mobile device 100. And, for example, when the wearable device 200adheres to the rear side of the mobile device 100, the mobile device 100can determine it as the wearable device 200 is located in the vicinityof the mobile device 100.

If the wearable device 200 is placed in the vicinity of the mobiledevice 100, the mobile device 100 receives device information of thewearable device 200 from the wearable device 200 using the communicationunit. For example, the device information of the wearable device 200 caninclude at least one selected from the group consisting of a shape, asize, and a resolution of a display unit 220 of the wearable device 200.And, the device information of the wearable device 200 includes a modelnumber and/or a unique number of the wearable device 200. The mobiledevice 100 can determine at least one selected from the group consistingof a shape, a size, and a resolution of a display unit 220 of thewearable device 200 based on information stored in advance.

Having received the device information of the wearable device 200, themobile device 100 displays an interface 305 for editing the first image301 on the first image 301 based on the device information. The wearabledevice 200 can make the mobile device 100 provide the interface 305 bytransmitting the device information of the wearable device 200 to themobile device 100.

The interface 305 has a form practically identical to the display unit220 of the wearable device 200. The interface 305 can be changed basedon a change of a relative position of the wearable device 200 for themobile device 100.

For example, as shown in FIG. 3b , if the display unit 220 of thewearable device has a circle shape, the interface 305 of a circle shapecan be displayed.

And, the interface 305 can be changed based on a position change changedby a user by moving the wearable device 200 or the mobile device 100between the wearable device 200 and the mobile device 100. For example,if the wearable device 200 is moved to the upper side in a manner thatthe user moves a left hand of the user to the upper side, the interface305 can also be moved to the upper side.

As shown in FIG. 3b , the interface 305 may have a boundary line. And,for example, the first image 301 in the interface 305 may differ fromthe first image 301 out of the interface 305 in terms of a chroma,brightness, contrast, and/or definition.

The mobile device 100 can provide the interface 305 to a positionclosest to the wearable device 200. Yet, if the wearable device 200 isplaced in the vicinity of the mobile device, the mobile device 100 mayprovide the interface 305 to a predetermined position. For example, thecenter of the display unit 120 of the mobile device 100 can beconfigured as an initial position of the interface 305.

The mobile device 100 can transmit a partial image (e.g., the firstimage 301 in the interface 305) corresponding to the interface 305 amongthe first images 301 to the wearable device 200. For example, if adistance between the mobile device 100 and the wearable device 200 isless than a first distance, the mobile device 100 can display theinterface 305. And, for example, the mobile device 100 can mirror thefirst image 301 in the interface 305 to the wearable device 200 afterthe interface 305 is provided.

After the interface 305 is displayed, if the distance between the mobiledevice 100 and the wearable device 200 exceeds a second distance, themobile device 100 can transmit a partial image corresponding to theinterface 305 among the first images 301 to the wearable device 200.Hence, a partial image of the first image 301 corresponding to a shapeof the display unit 220 of the wearable device 200 is transmitted to thewearable device 200.

As shown in FIG. 3c , having received the partial image, the wearabledevice 200 can display the received partial image on the display unit220.

Referring back to FIG. 3b , a user can call out the interface 305 byapproaching the wearable device 200 to the mobile device 100. The usercan transmit an image preferred by the user to the wearable device 200by simply moving the wearable device 200 away from the mobile device100. In particular, the user can copy a picture by simply attaching thewearable device 200 to the mobile device 100 and detaching the wearabledevice 200 from the mobile device 100. Meanwhile, the mobile device 100can transmit a partial image to the wearable device 200 based on aseparate input as well as the distance between the wearable device 200and the mobile device 100. For example, if an area in the displayedinterface 305 is touched, the mobile device 100 can transmit a partialimage of the first image in the interface 305 to the wearable device200.

Meanwhile, for example, the first image 301 can include a map image. Inthis case, the mobile device 100 can transmit a geographic coordinate tothe wearable device 200 instead of the partial image of the first image301. In particular, if the first image 301 corresponds to a map image,the mobile device 100 can transmit a geographic coordinate correspondingto a position of the interface 305 to the wearable device 200. Havingreceived the geographic coordinate, the wearable device 200 may start toguide a way based on the received coordinate.

When the mobile device 100 provides the interface 305 to the wearabledevice 200, the mobile device can provide auditory feedback or tactilefeedback to the wearable device 200 together with the interface 305.

The operations of the mobile device 100 and/or the wearable device 200mentioned earlier with reference to FIGS. 3a to 3c can be combined witheach other. In this case, the operations can be selectively combinedwith operations of the mobile device 100 and/or the wearable device 200to be explained in the following with reference to FIGS. 4 to 12.

FIG. 4 is a diagram for an example of moving an interface according toone embodiment.

Referring to FIG. 4(a), the wearable device is positioned at the rearside of the mobile device 100 and the interface 305 is displayed on thefirst image 301 of the mobile device 100. In this case, a user may wantto transmit a different part of the first image 301 to the wearabledevice.

In this case, as shown in FIG. 4 (b), the user may move the wearabledevice 200 in down direction. As a result, a relative position betweenthe mobile device 100 and the wearable device 200 is changed. The mobiledevice 100 moves a position of the interface 305 based on the change ofthe relative position. Hence, as shown in FIG. 4 (b), the interface 305is moves to the down direction of the mobile device 100.

In FIG. 4 (b), the position of the interface 305 is moved to the downdirection of the mobile device 100 by relatively moving the wearabledevice in down direction for the mobile device 100. Yet, the user canalso move the position of the interface 305 to the down direction of themobile device 100 by relatively moving the mobile device 100 in updirection for the wearable device 200.

The movement of the interface 305 shown in FIG. 4 is just an exampleonly. The user can move the interface 305 in any direction by changing arelative position of the wearable device for the mobile device 100. Theoperations of the mobile device 100 and/or the wearable device 200mentioned earlier with reference to FIG. 4 can be selectively combinedwith operations of the mobile device 100 and/or the wearable device 200explained in FIG. 3a and FIGS. 5 to 12.

FIG. 5 is a diagram for an example of magnifying an interface accordingto one embodiment.

Referring to FIG. 5 (a), the wearable device 200 is positioned in thevicinity of the rear side of the mobile device 100. In particular, theinterface 305 is displayed on the first image 301 based on a shape and asize of the display unit 220 of the wearable device 200. In this case, auser may want to transmit more partial images to the wearable device200.

Referring to FIG. 5 (b), the user moves the wearable device 200 toincrease a distance between the mobile device 100 and the wearabledevice 200. The mobile device 100 can increase a size of the interface305 based on the increased distance. For example, if a position of theinterface 305 is maintained for more than prescribed time, the mobiledevice 100 can change the size of the interface 305 based on thedistance between the mobile device 100 and the wearable device 200. And,if the distance between the mobile device 100 and the wearable device200 is maintained for more than prescribed time after the size of theinterface 305 is changed, the mobile device 100 can transmit a firstimage 301 corresponding to the changed interface 305 to the wearabledevice 200. Yet, the mobile device 100 may operate in a mode forchanging the size of the interface 305 based on an input inputted on asub interface described in the following. The mobile device 100 cantransmit a first image 301 in the changed interface 305 to the wearabledevice 200 based on the input inputted on the sub interface described inthe following.

Referring to FIG. 5 (b), the distance between the mobile device 100 andthe wearable device 200 is changed by moving the wearable device 200.Yet, the distance between the mobile device 100 and the wearable device200 can also be changed by moving the mobile device 100 and the size ofthe interface 305 can be changed based on the changed distance.

In this case, the distance change changed by moving the wearable device200 and the distance change changed by moving the mobile device 100 canbe performed as a different operation. For example, the mobile device100 can change a display size of the interface 305 based on a changeddistance only when the distance between the mobile device 100 and thewearable device 200 is changed by moving the wearable device 200.

The operations of the mobile device 100 and/or the wearable device 200mentioned earlier with reference to FIG. 5 can be selectively combinedwith operations of the mobile device 100 and/or the wearable device 200explained in FIG. 3a , FIG. 4 and FIGS. 6 to 12.

FIG. 6 is a diagram for an example of magnifying an image according toone embodiment.

As mentioned earlier in FIG. 5 (b), the size of the interface 305 can bechanged based on the distance between the mobile device 100 and thewearable device 200. Yet, a display size of the first image 301 can alsobe changed based on the distance between the mobile device 100 and thewearable device 200.

Referring to FIG. 6 (a), the wearable device 200 is positioned in thevicinity of the rear side of the mobile device 100. In particular, theinterface 305 is displayed on the first image 301 based on a shape and asize of the display unit 220 of the wearable device 200.

In this case, a user may want to magnify the first image 301. Referringto FIG. 6 (b), the user increases the distance between the mobile device100 and the wearable device 200 by moving the mobile device 100. Themobile device 100 displays the first image 301 in a manner of magnifyingthe first image based on the increased distance.

In particular, if the distance between the mobile device 100 and thewearable device 200 is changed due to the movement of the mobile device100, the mobile device 100 changes a display size of the first image 301based on the changed distance. For example, the mobile device 100 canmagnify the first image 301 on the basis of a position at which theinterface 305 is displayed.

Meanwhile, although the distance between the mobile device 100 and thewearable device 200 is changed due to the movement of the wearabledevice 200, the first image 301 can also be magnified.

And, if the distance between the mobile device 100 and the wearabledevice 200 is maintained for more than prescribed time after the size ofthe first image 301 is changed, the mobile device 100 can transmit afirst image 301 corresponding to the interface 305 to the wearabledevice 200. Yet, the mobile device 100 may operate in a mode forchanging the size of the first image 301 based on an input inputted on asub interface described in the following.

The mobile device 100 can transmit a first image 301 in the interface305 to the wearable device 200 based on the input inputted on the subinterface described in the following.

In this case, the distance change changed by moving the wearable device200 and the distance change changed by moving the mobile device 100 canbe performed as a different operation.
